DESCRIPTION

Mounting device for mounting an adapter device for fixing housing bodies in a car seat

The invention relates to a mounting kit and a method for mounting an adapter device for fixing housing bodies in a car seat, a mounting device and a mounting arrangement.

For certain application purposes it is desirable to secure the luggage for transport. For this purpose there are different solutions. On the one hand, the lower sides of the suitcases are held together and locked together on the side of the handle by means of a turning mechanism, whereby two suitcases are held against each other (see, for example, EP 2315701). On the other hand, side clips can be provided in a suitcase that can be operated when another suitcase is arranged on the existing one and then the two suitcases are locked together (see, for example, documents DE 19900361, and P 1238602).

Document US 2014/0263515 A1 discloses a base station that has a base and retention clamps. The retention clamps are configured to be adapted to the contour of a device. In addition, the base station has a locking system that is configured to secure the base to the lower seat anchors. The closure system comprises a band that can be adapted in length to the particularities by means of an adjustment loop.

Existing locks and interlocks are complex and prone to failures. In addition, it is partly unfavorable that the forces that occur are dissipated through the lid of the suitcase and a turning mechanism, so that these are prone to failures.

The handling and fixing of suitcases or other housing bodies of different sizes in an easy way for the user remain complicated.

An object of the present invention is to allow the user to assemble different housing bodies in a flexible and easy way.

This object is carried out by the contents with the characteristics according to the independent claims. Other embodiments are shown in the dependent claims.

In accordance with an embodiment of the present invention, a mounting kit is provided for mounting an adapter device for fixing housing bodies (in particular of at least one suitcase) in a

car seat, in which the mounting kit has a base body to be arranged in the car seat, connecting elements that (in particular by flexible connecting elements, such as straps or cables) are placed in the base body and they are designed to anchor the mounting equipment in fastening structures of the car seat, and it has a mounting structure in the base body, which is designed to mount the adapter device for fixing housing bodies.

In accordance with another embodiment of the present invention, there is provided a mounting device for fixing housing bodies in a car seat that has an adapter device for fixing housing bodies and mounting equipment with the characteristics described previously, in whose mounting structure the adapter device is mounted.

According to another embodiment of the present invention, a mounting arrangement is provided having a mounting device with the characteristics described above and at least one housing body that is attached to the adapter device.

In accordance with another embodiment of the present invention there is provided a method for mounting an adapter device to fix housing bodies in a car seat, so that in the procedure a base body of a mounting equipment is placed in the car seat, the mounting equipment is anchored in fastening structures of the car seat by means of connecting elements that are placed in the base body, and the adapter device for fixing housing bodies is mounted in a structure of mounting on the base body.

In accordance with an exemplary embodiment of the invention, a simple and effective possibility is achieved that an assembler who is using a car can safely and reliably carry different different housing bodies (such as suitcases for example) of different sizes, storage boxes, etc.). For this purpose, a base body is provided with a mounting kit with a mounting structure that can be rigidly fixed to a fixing structure of an adapter device - with coupling structures to receive different housing bodies. In the assembled state, the structures of Coupling of the adapter device are preferably placed free, so that the different housing bodies can be fixed in the adapter device in the assembled state thereof.

The connecting elements, which are fixed to the base body for example by means of flexible connection elements (such as straps or cables), can in turn be joined by a user to form a plug connection with fixing structures in the seat of car in order to provide a fastening of the mounting equipment to a support structure of the car (in particular in its body). Only by inserting the connecting elements into the fixing structures can a secured fixation of transport goods be achieved in the housing body (s) in the adapter device of the mounting equipment in the car, so that even during the running of the car It is possible for an assembler to easily carry transport goods with high security.

Further exemplary embodiments of the mounting equipment, mounting device, mounting arrangement and procedure will be described below.

According to an exemplary embodiment, the base body, which can be configured in particular as a carriage, can be made as a linkage construction, in particular a metal linkage construction. In this way, the mounting equipment can be configured light and, therefore, be taken with you by an even travel assembler. This can be further facilitated by the fact that in the adapter device, for example in the form of a plate, a recess is made as an equally lightweight carrying handle, so that a user can also use the adapter device mounted on the equipment Mounting as portable device. At the same time, said linkage construction forms a mechanically stable base for receiving an adapter device and at least one housing body mounted thereon.

According to an exemplary embodiment, the linkage construction can have first opposite rods, which in particular run parallel to each other, which extend along a seating surface (in particular from a backrest to a free end of the seat surface) of the car seat and are located below the adapter device in the mounted state of the adapter device.

According to an exemplary type of embodiment, the linkage construction can have second links opposite each other, in particular in the form of a loop, which extend, respectively, at least by sections in the direction along a back of the seat of automobile (and in particular perpendicular to the first linkages) and at least one of which extends vertically at least partially beyond at least a part of the adapter device in the assembled state thereof. The second linkages, which preferably extend vertically higher than the first linkages, deal with a secure support for the construction of linkage in the backrest and thus contribute to stability. Preferably the first linkages and the second linkages can be configured of light weight and of simple construction as curved and / or welded metal tubes with each other.

According to an exemplary type of embodiment, one of the second rods adjacent to the backrest can extend above substantially more vertical or higher along the backrest, in particular having a vertical extension length that is at least three times the length of vertical extension of another of the second linkages that forms one end of the base body farther from the backrest. Such a second linkage, particularly in the form of a loop, adjacent to the backrest can be of light weight and of simple construction to contribute to the care of the backrest and to protect it from damage, since said second linkage prevents direct contact of the bodies. housing mounted on the adapter device with the backrest, protecting it. Also by such construction an unwanted tilting of the mounting equipment together with the mounted adapter plate and the housing bodies can be avoided, even when the car accelerates or brakes rapidly.

According to an exemplary embodiment, the mounting structure (which extends in particular vertically and elongated, which advantageously leads to an introduction of vertical force) can have mounting holes in the base body and mounting bolts (in particular mounting screws) to pass through the mounting holes and through the corresponding fixing holes or other fixing structures of the adapter device, so that the adapter device can be mounted by introducing the mounting bolts into the mounting holes and fixing holes and by fixing (in particular screwing) the mounting bolts in the mounting holes and / or the fixing holes in the mounting equipment. The mounting holes of the mounting structure can be implemented elongated as hollow spaces in a respective tube part, the tube part being able to be part of the linkage construction or it can be fixedly attached (for example, welded) to the linkage pieces individual This produces a highly stable connection between the mounting equipment and the adapter device, and even allows the fixing of heavy housing bodies. Preferably, a four-point fixation is provided by the mounting structure between the adapter device and the mounting equipment.

According to the invention, the connecting elements can be made as Isofix connecting elements that are designed for anchoring in Isofix fastening structures of the car seat. Isofix fastening structures provide a secure and easy-to-handle fastening system so that an adapter device can receive different housing bodies in a car seat, in which a rigid connection is made between the body and the housing bodies through the mounting equipment. The Isofix fastening structures of the car seat are standardized in correspondence with the ISO 13216 standard (in particular in the 1999 or 2004 or 2006 version) and, therefore, are included as standard in many car seats. The Isofix fastening structures of the car seat have two retention brackets that are at a fixed distance from each other in a space between the backrest surface and the seat surface of the car seat. The connecting elements of the mounting equipment can be hooked into this retaining bracket and fixed thereto forming a clamping joint.

According to an exemplary type of embodiment, the one, two or more connecting elements can be made by means of retention hooks, which are applied, for example by a click function, on a respective retention bracket (for example, to form a U-shaped receiver lug) of the fastening structures in the car. When the connecting elements of the mounting equipment are attached to such a retaining bracket, the retaining hooks are interlocked in the retaining stirrups forming a rigid connection.

Advantageously, in addition to the fixing on the retention brackets, a second fixing of the mounting equipment on the car seat can be carried out. This second fixing can be done, for example, by a seat belt in the car seat. Measures can be taken to secure the seat belt to the mounting equipment and / or to the adapter plate.

According to an exemplary type of embodiment, the connecting elements can be fixed to the base body by means of flexible connecting elements, in particular connecting straps and / or connecting cables. Such flexible connection elements may, on the one hand, have the tensile strength necessary to ensure a firm connection of the mounting equipment with the car seat and allow a user in the same way a comfortable handling of the connecting elements before securing Flexible connection elements. In other words, a user can manually extract the connector elements, for example from a connector element receptacle, and take them to a plug connection with the motor vehicle law fixing structures. Thus, the flexible connection elements allow the user a handle that can be freely selected. If a tensile force is exerted then the flexible elements can be secured. Advantageously, during securing the connecting elements are retracted in the connector element receptacles, which (for example, due to a positively shaped fit of the connecting elements and the connector element receptacles) preferably results in a theoretical orientation defined of the connecting elements.

In accordance with an exemplary embodiment, the mounting equipment may have a tensioning device that can be operated by a user to tension the flexible connection elements after anchoring the connecting elements in the fixing structures forming a connection resistant to the traction. The tension device can be made as a user-manageable clamp, through which one end of the flexible connection elements can be introduced, pulled hard and then by actuation of the clamp can be fixed in a tensioned state. The tensioning device can preferably be arranged on one side of the mounting equipment opposite the back of the car seat and can be freely operated in this position by a user. The flexible connection elements can be guided on a lower side of the adapter device or in an intermediate space between the adapter device and a seat surface of the car seat between linkages of the base structure. Thus, by the flexible connection means a disturbance of the assembly or disassembly of housing bodies on a housing surface of the upper side of the adapter device is prevented.

According to the invention, the mounting equipment has a guide receptacle (or connector element receptacle) arranged in the base body for the guided housing of the connector elements. In an unused state, the connector elements can be housed in a respective guide receptacle saving space and, if necessary, can be manually removed from the respective guide receptacle by a user.

According to an exemplary type of embodiment, the connecting elements can be made to be anchored in fastening structures between the backrest and the seat surface of the car seat, and thus provide an anchor inside the car seat. If the fixing structures are fixed to the car body, a particularly stable fixing is possible.

According to an exemplary embodiment, the mounting equipment may have an adjustment device, which is configured to adjust a height and / or an inclination angle of the adapter device mounted on the mounting equipment. In some cars the seat surface is in an inclined position. This can lead to unwanted slipping of housing bodies or transport goods during arrangement of housing bodies in the adapter device by the resulting inclined work surface. An aid is provided here by the aforementioned adjustment device, with which a user can adjust an inclination angle of the mounting equipment, so that the adapter device is in a horizontal or at least approximately horizontal position. This can be achieved, for example, if telescopic bars of the base body of the mounting equipment are provided with fixing holes, so that a user can adjust a desired inclination angle of the adapter device with respect to the seating surface by introduction of a fixing element (for example a bolt) in a selected fixing hole.

According to an exemplary embodiment, the mounting equipment may have wheels, which are arranged on the lower side of the base body so that the mounting equipment can be moved by rolling in a state separate from the car seat. In this way, the assembly equipment can be transported to a desired position by simple means. Preferably, the wheels can be locked by actuating a locking device to prevent the mounting equipment, together with the adapter device and possibly the housing bodies mounted therein, from rolling out.

According to an exemplary embodiment, the adapter device may be made to fix housing bodies of different sizes. This further increases the flexibility in fixing different housing bodies in the adapter device.

The adapter device may have a support device for supporting a fixed housing body, first coupling structures in the support device that are made for fixing a first housing body of a first size by means of displacement and locking in the first structures of coupling, and second coupling structures in the support device that are made for the fixing of a second housing body of a second size by means of displacement and interlocking in the second coupling structures. In accordance with an exemplary embodiment of the invention, an adapter device is provided that is easy to handle by a user and so that housing bodies of different sizes (eg suitcases) can be intuitively brought to different connection states. . With a simple operation, a user can bring a housing body that is in a connection state with the adapter device also back to another connection state or a separation state. In particular, when this housing body is again separated from the adapter device, it is free to receive another housing body, for example of different size. This can be achieved with a simple and intuitive movement of displacement and interlocking, which is handled similarly inverse to separate the connection. Therefore, with a single plate-shaped adapter device, different housing bodies of different sizes can be temporarily fixed by a universal system of coupling structures. This allows a user to assemble in a modular or construction kit type discretionary combinations of adapter devices and housing bodies to form a common body.

According to an exemplary embodiment, the support device may be made as a support plate. Then, the support device can serve as a flat and vertically compact housing platform with a large mounting surface to support the housing body (s).

According to an exemplary embodiment, the first coupling structures may have at least a first guide rail, in particular two first guide rails parallel to each other and separated a first distance from each other, so that the first housing body it can be moved to a first interlocking position along the at least one first guide rail. The at least one first guide rail, but particularly advantageously, a pair of first guide rails parallel to each other, offers the user an intuitive possibility of mounting the first housing body on the adapter plate with correct positioning and, therefore, robust against failures.

According to an exemplary embodiment, the second coupling structures may have at least a second guide rail, in particular two second guide rails parallel to each other and separated from each other a second distance different from the first distance, being movable the second housing body to a second interlocking position along at least a second guide rail. Preferably, the at least one second guide rail, preferably a pair of second guide rails parallel to each other, are correspondingly made to the at least one first guide rail, but at the same time takes into account the other size of the second housing body. A user can recognize at a glance how the at least one second guide rail must be driven in relation to the at least one first guide rail to mount the respective housing body. The pair of second guide rails may be arranged parallel to the pair of first guide rails and the latter may even be arranged laterally.

According to an exemplary type of embodiment, the first coupling structures may have at least one first interlocking body, in particular at least two interlocking bodies spaced along at least one first guide rail, so that the at least one First interlocking body is made to lock the first housing body to the adapter device detachably vertically in the first interlocking position when the first housing body is moved along at least a first guide rail to the first position of interlocking The at least one first interlocking body can be inserted, for example, above the at least one first guide rail, that the corresponding coupling structures of the first displaced housing body are arranged in at least one first guide rail and by the at least one first interlocking body disposed above prevents a vertical detachment. The insertion of the at least one first interlocking body through the at least one first guide rail is preferably carried out before the insertion of the first housing body, but alternatively it can also be carried out even after the insertion of the first body of accommodation.

According to an exemplary embodiment, the second coupling structures may have at least a second interlocking body, in particular two or more second interlocking bodies spaced along the at least a second guide rail, so that the at least A second interlocking body is made to interlock the second housing body to the adapter device in a non-removable manner vertically when the second housing body travels along at least a second guide rail to the second interlocking position. For example, the at least a second interlocking body can be inserted above the at least a second guide rail on it, so that corresponding coupling structures of the second displaced housing body are arranged in the at least a second guide rail and by the at least a second interlocking body disposed above a vertical detachment is avoided. The insertion of the at least a second interlocking body through the at least a second guide rail is preferably carried out before the insertion of the second housing body, but alternatively it can also be performed only after the insertion of the second housing body.

The number of first interlocking bodies and the number of second interlocking bodies can be different and, for example, can be selected based on what weight the respective housing body has. The greater this weight, the greater the number of first or second interlocking bodies may be chosen.

According to an exemplary type of embodiment, the at least one first interlocking body and / or at least a second interlocking body (in particular before an interlocking or to interlock the respective housing body) may or may be displaced (s) angularly (in particular, perpendicularly) to a respective guide rail (in particular, they can be movable leaving a vertical space open between a base of the respective guide rail and the respective interlocking body in the respective guide rail). Also several first or second interlocking bodies can be arranged in the respective common support structure (in particular rigid) to be collectively displaced by a user further facilitating the handling.

According to an exemplary type of embodiment, the first coupling structures and / or the second coupling structures may be made such that the first housing body or the second housing body can be stacked in the adapter device selectively of a vertically secured detachable manner against displacement by means of the coupling structures, and / or that the respective housing body and the adapter device can be coupled to each other in a non-removable manner vertically by displacement and interlocking in the first coupling structures and / or in the second coupling structures. The respective housing body can therefore be stacked or selectively coupled in combination with the adapter device. Advantageously, a housing space of the housing body in the stacked or coupled state will remain accessible from the outside. In particular, a housing body made as a suitcase in the stacked or coupled state can still be transferred between an open state and a closed state. Thus, even in the coupled or stacked state, a user can access the interior of the housing body of the housing arrangement.

In the state of vertically removable stacking, but secured against displacement in a horizontal plane, it is possible for a user to separate the housing bodies from the bodies connected with it (i.e. housing bodies and adapter device) by simple vertical lifting of the adapter device On the other hand, in this state, however, it is impossible for one body to be displaced horizontally with respect to the other body. Therefore, in this state of operation the bodies are secured against one another against sliding, but they can be separated from each other immediately by a single movement of the hand. This operating state is therefore suitable for temporarily stacking the two bodies.

However, alternatively, the bodies (i.e., the housing body and the adapter device) can also be coupled to each other in a non-removable manner vertically, that is, to be joined together in such a way that the separation of the two bodies does not It is possible with a simple vertical lifting movement. A separation of the two bodies is possible in this operational state only by the relative displacement of the two bodies along a direction of horizontal displacement. It is also possible that, from this connection state coupled in a non-detachable manner, exerting a purely vertical force, the coupled bodies can also be immobilized in a horizontal plane, for example exerting a fixing force that acts perpendicular to a direction of displacement of the bodies, for example by means of a retaining joint to couple the two secured bodies against displacement, also horizontally.

According to an exemplary embodiment, the at least one first interlocking body and / or the at least one second interlocking body may or may be made such that the first housing body or the second housing body can be stacked in the adapter device detachably vertically secured against displacement by means of a respective one of the interlocking bodies. For this, it is advantageously possible that at least one respective locking body protrudes vertically raised above an area of the respective guide rail that surrounds it, so that (advantageously protruding from the bottom side starting from the housing body) retention feet can be placed (or the like) of the housing body to be housed for stacking on this raised interlocking body. This it allows a particularly compact embodiment of the adapter device, since the interlocking bodies can functionally contribute to both coupling and stacking.

According to an exemplary type of embodiment, the adapter device may have at least one stop structure, in folding and folding position with respect to the support device, which is designed so that after moving the first housing body and / or the second housing body, the respective housing body collides with the at least one stop structure in an interlocking position in which the respective housing body can be interlocked or is interlocked in the adapter device. Such a stop structure has the advantage that even without visual contact (for example, in case of mounting in a poorly lit or optically accessible car boot), it intuitively shows the user when a housing body to be mounted on the device adapter has reached its desired fixing position. This increases user comfort and reduces the risk of improper handling. However, the ability to be retracted or collapsed from such stop structures also allows several adapter devices to be coupled one after the other, to move a housing body towards a rear adapter device, even without visual contact, without being disturbed by a top structure.

In accordance with an exemplary embodiment, the first coupling structures and / or the second coupling structures may also have a first additional locking device for additionally locking the first housing body when it is displaced and secured against displacement. interlocked in the support device and / or a second additional interlocking device to additionally securely lock the second housing body when it is displaced and interlocked in the support device. By at least one additional interlocking device in at least one of the bodies to be joined (ie, adapter device and housing body), preferably by corresponding coupling structures in the two bodies coupled to each other, a third state can be defined of connection, that in the non-detachable vertically coupled state of the two bodies a relative displacement of the same is possible in addition to each other (for example, by deactivation of the additional interlocking device) or a relative displacement of each other is impossible (for example, by activating the additional interlocking device). In order to reliably secure the two bodies with each other (for example, for a car trip), the two additional interlocking devices can be interlocked in a reversible manner.

According to an exemplary embodiment, the adapter device may have fixing holes for fixing the adapter device in the mounting equipment, in particular fixing holes for receiving mounting bolts of the mounting structure of the mounting equipment. For example, a fixation can be made between the adapter device and the mounting equipment in four corner regions of the adapter device and in four corresponding corner regions of the mounting equipment.

According to an exemplary embodiment, the housing body can be a suitcase for transporting transport goods, a first suitcase of a first size and a second suitcase of a second size, another adapter device and / or a storage box. These and other housing bodies can be combined with each other in almost any way thanks to the construction kit system according to an exemplary embodiment of the invention.

According to an exemplary embodiment, the mounting equipment can be additionally fixed to the car seat by means of a passenger seat belt. Therefore, in addition to the attachment to the fastening structures of the car seat, the belt that is in the car seat can also be used to provide additional fastening of the mounting equipment. In this way the reliability is further increased.

The same or similar components in the different figures are provided with the same reference numbers.

Before describing exemplary embodiments of the invention with reference to the figures, some general aspects of the invention will be explained.

In accordance with an exemplary embodiment of the invention a mounting kit is provided for attaching an adapter plate to an Isofix interface, so that the mounting kit can have a base body to be placed in a passenger seat of A car and on the front side can have two Isofix connections or connector elements. The latter can be tightened and immobilized on the rear side by means of a traction band in a receptacle of connecting element to be able to firmly attach the mounting equipment to the seat back. Optionally, a U-profile can also be provided that extends along the backrest to protect the seat against wear or damage during operation of the coupling device, and thus care for it. The base body can be integrally screwed to a plate-shaped adapter device by means of a mounting structure. Such an adapter device can be provided for fixing housing bodies of different sizes. Such an adapter device can be mounted on a larger body. In the adapter device a large suitcase or a small suitcase or other housing body can be mounted discretely by sliding and interlocking by means of movable interlocking elements in the adapter device. Likewise, it may be possible to stack the large suitcase or small suitcase or other housing body on a discretionary basis in the adapter device, for which interlocking elements can be placed in a position where they can receive positively shaped feet suitcase stacking.

An adapter device according to an exemplary embodiment of the invention can be used for the connection of suitcases of different sizes. A respective suitcase can also be moved between two adapter devices arranged one after the other. The adapter device can be provided with a carrying handle to be transported and can be fixed to a wall. The fixing holes or other fixing structures for fixing the adapter device to a wall can be the same with which the adapter device can also be screwed to a base body. The adapter device may be provided with steel reinforcements to increase the rigidity of the adapter device. In addition, for example, projections may be provided in the form of a mushroom in the adapter device that may be designed to be applied in grooves formed inversely in another adapter device of the same type. In this way, several adapter devices can be placed next to each other.

A mounting device with a base body for receiving an adapter device allows a coupling of the adapter device with Isofix fixing means. A fastening of such mounting equipment in a car, in particular in a car seat, can be carried out by means of a seat belt and / or through the Isofix connection means. The base body can be provided adjustable in height, so that for example in the case of inclined seating surfaces a horizontal work surface can be adjusted. This can be done, for example, by means of a grid of holes at different heights, in which a fixing bolt or the like can be inserted, so that a plate or the adapter device can be engaged in different height positions. Due to a symmetrical structure of the adapter device it is possible to mount this by means of the mounting equipment in a discretionary seat in the car, in particular a front seat or a rear seat.

Figure 1 shows a housing body 10 made as a suitcase according to an exemplary embodiment of the invention in an open state. Figure 2 and Figure 3 show the housing body 10 according to Figure 1 in the closed or closed state. Figure 4 shows a housing body 10, as shown in Figures 1 to 3, in a state coupled to another housing body 10 'of the same type, made as a suitcase. Figure 4 shows, therefore, an arrangement 99 showing the housing body 10 and the additional housing body 10 'of the same type in a connection state.

The housing body 10 serves to transport goods to be transported. Such merchandise to be transported can be housed loose or fixed or secured inside the housing body 10 and can be accommodated in particular in accommodation receptacles (not shown), which in turn are safely housed inside the body. of accommodation 10 when it is in a closed state. Examples of such transport goods are consumables (such as screws, nails, dowels, bulk materials or liquids) or tools (such as screwdrivers or drill bits), etc.

The housing body 10 has a body 12 and a cover 14 attached or that can be attached to the body 12. On the inner sides of the body 12 reinforcement ribs 28 are formed for the mechanical reinforcement of the housing body 10. According to the example of embodiment shown various coupling structures 30, 32, 34, 36, 38, 40, 44 are placed exclusively in the body 12, but not in the cover 14. In the closed state, a body is enclosed between the body 12 and the cover 14 accommodation space to receive goods to be transported inaccessible from the outside between the body 12 and the cover 14. In the open state, the accommodation space can be accessed from the outside, for example to extract transport goods outside the housing body 10 or insert them into the housing 10.

The coupling structures 30, 32, 34, 36, 38, 40, 44 are realized in such a way that the housing body 10 and the other housing body 10 'identical can be stacked on each other discretionally in a vertically removable manner and secured against horizontal displacement (state I) by means of the coupling structures 30, 32, 34, 36, 38, 40, 44 (which are therefore also provided identically in the other housing 10 ') or can be coupled to each other in a non-detachable way vertically and horizontally movable (state II). Furthermore, the housing bodies 10, 10 'can be vertically detachable and not horizontally movable (state III). The coupling structures 30, 32, 34, 36, 38, 40, 44, which provide both the stacking (state I) and the coupling (state II, state III) of the various housing bodies 10, 10 ', are made exclusively by means of measurements in the respective body 12 (see the retention projections 30 and the housing grooves 36 of retention feet 34, coupling heels 38 on the retention feet 34, a guide rail 30, 32 between the retention projections 30 and steps 32, as well as retention slides 40 and housing grooves 44 that cooperate with each other), without having taken measures in the cover 14.

To activate state I, the other housing body 10 'is arranged vertically on the housing body 10 and then is lowered onto the housing body 10, so that the housing slots 36 on the retaining feet 34 of the other body of housing 10 'are applied with the retention projections 30 of the housing body 10. The housing grooves 36 in the retention feet 34 of the other housing body 10', as well as the retention projections 30 of the housing body 10, they take care that the other housing body 10 'at any time can be lifted vertically from the housing body 10 (i.e., by an inverse movement to the stacking movement), but is protected by the positive connection of form between the grooves of housing 36 on the retention feet 34 of the other housing body 10 'and the retention projections 30 of the housing body 10 in the event of a possibility of movement in a horizontal plane

To activate state II, the other housing body 10 'is arranged in the horizontal plane in front of the housing body 10 and raised vertically slightly in relation to the housing body 10, so that the coupling heels 38 of the other body of housing 10 'are arranged at the height between the retention projections 30 and the steps 32, therefore at the height of the guide rails 30, 32 of the housing body 10. Then, the activation of state II is completed by moving the another housing body 10 'on the housing body 10, so that the coupling heels 38 of the other housing body 10' are inserted between the retention projections 30 and the steps 32, therefore in the guide rails 30, 32 of the housing body 10. In state II, a lifting of the other housing body 10 'of the housing body 10 is impossible due to the positive connection between the coupling heels 38 on one side and the retention projections 30 or the steps 32, therefore with the guide rails 30, 32, on the other hand. At the same time a separation of the housing body 10 from the other housing body 10 'is possible by a horizontal displacement of the another housing body 10 'away from the housing body 10, specifically with a reverse displacement movement in comparison with which state II was completed.

To activate state III starting from state II, the retention slides 40 of the other housing body 10 'are inserted into the housing grooves 44 of the housing body 10' in the state of the housing bodies 10, 10 'offset one towards another by a movement of vertical displacement. In state III thus completed, a protection against displacement between the housing bodies 10, 10 'is now also formed, so that now neither a vertical elevation nor a horizontal displacement of the housing bodies 10, 10' is relatively possible each.

A part of the coupling structures 30, 32, 34, 36, 38, 40, 44 (specifically the coupling structures with reference numbers 30, 34 with 38) contribute to both the stacking secured against displacement and vertically detachable, such as to the coupling with each other not detachable vertically.

As already described, the coupling structures 30, 32, 34, 36, 38, 40, 44 are made so that the housing body 10 and the other housing body 10 'can be selectively displaced towards each other in the state coupled to each other vertically detachable by means of coupling structures 30, 32, 34, 36, 38, 40, 44 (state II in which the coupling structures 40, 44 are not applied to each other) or can be displaced towards one another by actuating the coupling structures 30, 32, 34, 36, 38, 40, 44 (state III, in which additionally the coupling structures 40, 44 are applied to each other). A part of the coupling structures 30, 32, 34, 36, 38, 40, 44 (specifically the coupling structures with reference numbers 40 and 44), which in state III coupled one above the other in a secured manner against the displacement and not removable vertically contribute to the assurance against displacement, is realized and can be operated independently of another part (specifically the coupling structures with the reference symbols 30, 32, 34, 36, 38) of the coupling structures 30, 32, 34, 36, 38, 40, 44 that contribute to the vertically secured detachable stack against displacement or to the coupling with each other not vertically removable (state I or state II).

The part of the coupling structures 30, 32, 34, 36, 38, 40, 44, with which the housing body 10 and the other housing body 10 'can be stacked together on one another in a vertically detachable manner and secured against displacement is made in the form of retention projections 30 in the outer edge areas of the upper side of the body 12, as well as in the form of retention feet 34 with housing grooves 36 of the lower side that cooperate with the retention projections 30 in the stacked state in the outer edge regions by the lower side of the body 12.

The part of the coupling structures 30, 32, 34, 36, 38, 40, 44, with which the housing body 10 and the other housing body 10 'can be coupled to each other in a non-removable manner vertically they are made in the form of guide rails 30, 32 in the outer edge areas on the upper side of the body 12, as well as in the form of coupling heels 38 on the lower side in the regions of the outer edge on the lower side of the body 12, which cooperate with the guide rails 30, 32 in the coupled state. The retention projections 30 are part of the guide rails 30, 32 and the coupling heels 38 are part of the retention feet 34. The retention feet 34 extend vertically beyond a lower surface of the body 12 downwards ( see Figure 2), so that the housing body 10 can be deposited with the retaining feet 34 on a lower base.

The part of the coupling structures 30, 32, 34, 36, 38, 40, 44, with which the housing body 10 and the other housing body 10 'in the state coupled to each other cannot be vertically detachable can be secured facing displacement (state III), it is made in the form of housing grooves 44 and retention slides 40 that cooperate with them. As indicated by an arrow 42 in Figure 1, the retention slides 40 in the body 12 of the other housing body 10 'can be introduced into the housing grooves 44 in the body 12 of the housing body 10 (when the other housing body 10 'is arranged above the housing body 10, as in Figure 4), or vice versa (when the housing body 10 is disposed above the other housing body 10').

All coupling structures 30, 32, 34, 36, 38, 40, 44 are provided on lateral surfaces of body 12 (see, for example, figure 1). In contrast, the cover 14 of the coupling structures 30, 32, 34, 36, 38, 40, 44 is free.

The housing body 10 also has recessed handles 26 in the form of depressions on opposite side surfaces of the body 12.

In addition, an optional closing device 46, 48, 50, 52 may be provided to close the lid 14 on the body 12 in the closed state. In the closed state of the housing body 10 an interlock can be provided with a counterpart 48 of the cover 14 by means of a key 50 in a turning lock 52 in a housing element 46 of the body 12. When the cover 14 is tilted by means of a hinge 16 to close the interior of the body 12, then the closing elements of the pivot lock 52 in the body 12 engage with the counterpiece 48 in the cover 14. The pivot lock 52 in the body 12, which can be operated by means of the removable key 50, contains a tilting stirrup that is inserted into the counterpart 48 in the cover 14.

A handle 54 is placed in a cavity on an upper lateral surface of the body 12 in the support state and can be inclined between a retracted state on the lateral surface of the body 12 (see Figure 1) and an unfolded state of the lateral surface . A transition between these two states can be achieved by the user by manipulating the handle 54. The handle 54 is formed by a hard component 56 to stabilize and support the handle 54 and a soft component 58 for a comfortable touch of the housing body 10 for a user who supports it. The handle 54 in the body 12 can be applied to the latter and remains there in a compact position by the action of a retention projection that engages the handle 54 in the introduced state. In the area of the handle 54 a tag area 75 is provided in which an identification support can be inserted, indicative for example of the content of the housing body 10.

The housing body 10 also has the hinge 16, which connects the body 12 and the cover 14 foldably with each other and is made to be able to deploy the housing body 10 between the closed state and the open state. The retaining feet 34 and the hinge 16 are structurally adapted and positioned, so that the hinge 16 remains spaced apart from the bottom base when the housing body 10 rests on the bottom base by means of the retention feet 3. 4.

As can be recognized in Figure 1, a document holder 68 is arranged on an inner side of the cover 14 with which documents not shown in Figure 1 can be temporarily attached and, therefore, can be fixed during the transport

Both the body 12 and the cover 14 are made, respectively, from the standpoint of manufacturing simply as an injection molded part. Other components are subsequently attached to the respective injection molded part (for example, the retention slide 40 in the body 12 or the document holder 68 in the cover 14).

The housing bodies 10, 10 'are also made to receive assortment boxes (not shown) in which for example tool materials such as screws, dowels or others can be housed. In the closed state of the respective housing body 10, 10 ', the assortment boxes are secured inside the respective housing body 10, 10' inaccessible to a user, while in the open state of the housing body 10, 10 'respective a user can access the assortment boxes.

As shown in Fig. 1 and Fig. 2, on an inner side of the body 12, longitudinal struts 18 and cross struts 20, which are cut in the shape of a cross, protrude high on a flat bottom. In the ^cutting areas of ^{the longitudinal struts} 18 ^{and the transverse struts 20 additional} raised ^{frames 22} are formed, which form in each cutting area together with the longitudinal struts 18 and the cross struts 20 four housing depressions 24 to receive feet of assortment boxes shaped substantially inverse to that of housing depressions 24.

An annular shaped depression on an inner side of the cover 14 is covered with an annular shaped pass-part 64 that is peripherally welded to the cover 14. In the pass-part 64, the document holder 68 is placed by plastic clips 66 Plastic to hold documents not shown.

Figure 5 shows an upper side and Figure 6 shows a lower side of a plate-shaped adapter device 100 according to an exemplary embodiment of the invention. While two housing bodies 10, 10 'of the same type and of the same size can be fixed directly to each other (see Figure 4), the adapter device 100 allows for example to accommodate housing bodies 10, 102 of different sizes made with fixing as a suitcase (see for example figure 13, figure 18), contribute to the fixing of a housing body 352 made as a storage box (see for example figure 11) or also between two housing bodies 10, 102 of different size (see for example figure 19) act as an intermediate piece that produces a fixation. It is also possible to fix two housing bodies 10, 102 of the same size (for example, suitcases).

For this, the adapter device 100 has a support device 104 made as a plastic support plate to support a fixed housing body 10, 102. In addition, the adapter device 100 contains first coupling structures 106 to 108 in the support device 104 which are made for fixing a first housing body 10 of a first size by displacement and locking in the first coupling structures 106 to 108 (see, for example, figure 13). In addition, the adapter device 100 has second coupling structures 110 to 112 in the support device 104, which are made for fixing a second housing body 102 of a second size (larger compared to the first size) by displacement and interlocking in the second coupling structures 108 to 110 (see, for example, figure 18).

The first coupling structures 106 to 108 contain two first guide rails 106 parallel to each other and separated a first distance from each other. As Figure 13 shows, the first housing body 10 can be moved along the first two guide rails 106 to a first interlocking position, in which the retaining feet 34 of the first housing body 10 slide to along the first guide rails 106. Correspondingly, the second coupling structures 110 to 112 have two second guide rails 110 parallel to each other and separated from each other a second distance larger than the first distance and laterally surrounding the first guide rails 106. As shown in Fig. 18, the second housing body 102 (which is larger than the first housing body 10) can travel along the second guide rails 110 to a second position of interlocking on the support device 104, so that the retaining feet 34 of the second housing body 102 slide along the second rails of guide 110.

In addition, the first coupling structures 106 to 108 contain, respectively, two first interlocking bodies 108 spaced along the respective first guide rail 106. Correspondingly, the second coupling structures 110 to 112 contain, respectively, three second interlocking bodies 112 spaced along the respective second guide rail 110.

In the position of the locking bodies 108, 112 shown in Figure 5, a respective housing body 10, 102 can be placed in the adapter device 100 by a vertical descent, whereby the respective locking bodies 108, 112 penetrate in the housing slots 36 on the retaining feet 34 of the respective housing body 10, 102, and thus adopt a state 1 secured against displacement, vertically detachable (analogous to the previous state I between two housing bodies 10, 10 'of the same kind). In other words, the respective interlocking bodies 108, 11, 2 in state I act similarly to the retention projections 30 of the housing bodies 10, 10 'in state I).

By moving the first housing body 10 along the first two guide rails 106 to the first interlocking position (which can be intuitively indicated by a stop structure 114 described in more detail below, against which a lateral surface of the first housing body 10 during the movement, when the first interlocking position has been reached) the two pairs of first interlocking bodies 108, on the contrary, cause a vertically non-detachable interlocking of the first housing body 10 in the adapter device 100 (this position may be designated as state 2 in analogy with state II above). By moving the second housing body 102 along the two second guide rails 110 to the second interlocking position (which in turn is defined by the stop structure 114 described in more detail below), the second body of housing 102 is interlocked in the adapter device 100 in the second locking position by the second locking bodies 112 in a non-removable manner vertically (state 2 of the second housing body 102).

As indicated by the arrows on the respective interlocking bodies 108, 112 in Figure 5, to interlock the respective housing body 10, 102 the first and second interlocking bodies 108, 112 can be displaced before perpendicular to the extension directions of the guide rails 106, 110 and adopt an interlocking position in a respective guide rail 106, 110 - leaving a vertical intermediate space free between the respective interlocking bodies 108, 112 and the respective guide rail 106, 110 to accommodate a respective retaining foot 34 of the respective housing body 10, 102. In Fig. 5, the interlocking bodies 108, 112 are all displaced projecting in the respective associated guide rail 106, 110 and have been locked in this position. For example, during the movement of a housing body 10, 102 along the guide rails 106, 110 aligned between several adapter devices 100 assembled together, completely free the guide rails 106, 110, the locking bodies 108 , 112 can be moved completely out of the guide rails 106, 110 by a movement opposite the direction indicated by the arrow. As can be recognized in FIG. 6 and FIG. 7, respective sets of interlocking bodies 108 or 112 are provided in common support strips 187, 189 rigidly or as an integral part thereof, so that the support strips 187, 189 they can be moved between an external retention position (by introducing the respective interlocking bodies 108, 112 into the respective guide rails 106, 110 to bring the adapter device 100 to a position that allows the interlocking) and an internal retention position (by displacement of the respective interlocking bodies 108, 112 out of the respective guide rail 106, 110 to completely free the guide rails 106, 110).

The described configuration of the first coupling structures 106 to 108 and the second coupling structures 110 to 112 allows optionally only the first housing element 10 or only the second housing body 102 can be carried by means of the coupling structures 106 at 108, 110 to 112 in the adapter device 100, or to a stackable state that can be dismantled vertically and secured against displacement (state 1) or by means of displacement and interlocking in the first coupling structures 106 to 108 or the second coupling structures 110 to 112 to a state coupled to each other in a non-detachable manner vertically (state 2):

If the housing body 10 shown in Figures 1 to 4 is placed by vertical descent on the adapter device 100 in the position of the locking bodies 108, 112 according to Figure 5, the housing slots 36 are applied to the retaining feet 34 of the housing body 10 (see Figure 3) with vertical projections of the first interlocking body 108 of the adapter device 100, which according to Figure 5 are partially inserted into the first guide rails 106. The housing grooves 36 on the retaining feet 34 of the housing body 10, as well as the projections of the first locking bodies 108 of the adapter device 100 ensure that the housing body 10 can be raised again vertically from the adapter device 100 at any time (i.e., by an inverse movement to the stacking movement), but be protected by the positive connection between the housing grooves 36 on the retaining feet 34 of the housing body 10 and the projections of the first interlocking bodies 108 before a possibility of displacement in a horizontal plane (state 1).

To instead activate the state 2 coupled to each other in a non-removable manner vertically, the housing body 10 can be arranged (for example, slightly inclined with respect to the horizontal plane) in front of the adapter device 100 according to Figure 5, so that the coupling heels 38 on the front side of the housing body 10 are arranged on the first guide rails 106 between the respective first interlocking bodies 108 on the front side and the first respective interlocking bodies 108 on the rear side of the adapter device 100. Then, the activation of the vertically non-detachable coupled state 2 is completed by lowering the housing body 10 completely in the horizontal plane, so that the coupling heels 38 on the rear side of the housing body 10 penetrate the first guide rails 106. Next, the housing body 10 thus positioned is displaced along s first guide rails 106 until both the coupling heels 38 on the front side and the coupling heels 38 on the rear side are positioned below the respective first interlocking bodies 108. In this state 2, it is impossible to lift the housing body 10 of the adapter device 100 due to the positive shape connection between the coupling heels 38, on the one hand, and the first interlocking bodies 108 or the first guide rails 106, on the other hand. At the same time, the separation of the housing body 10 from the adapter device 100 is possible by horizontal displacement of the housing body 10 outwardly from the adapter device 100, specifically with a reverse displacement movement to that with which the coupled state 2 was activated each other in a non-detachable way vertically.

The first coupling structures 106 to 108 further include a first additional locking device 107 in the form of housing grooves in the support device 104 to additionally securely lock the first housing body 10 when it is displaced and locked. in the support device 104 and, therefore, is in state 2. If the coupling heels 38 of the first housing body 10 are arranged below the projections of the first interlocking bodies 108, a displacement is still possible linear of the first housing body 10 along the first guide rails 106. To start from this state 2 not secured against displacement activate a state 3 secured against displacement (in analogy to the state III insured against displacement described above between housing bodies 10, 10 'of the same type), in state 2 displaced or not on the other of the first housing body 10 and of the adapter device 100 by means of a vertical displacement movement, the retention slide 40 of the housing body 10 is introduced into the housing slots of the first additional interlocking device 107. Then it is formed a safe against displacement between the first housing body 10 and the adapter device 100, so that now neither a vertical lift nor a horizontal movement of the first housing body 10 away from the adapter device 100 is possible. Correspondingly, the second coupling structures 110 to 112 have a second additional interlocking device 111 in the form of housing grooves in the support device 104 to additionally securely lock the second housing body 102 when it is displaced and locked in the support device 104.

If the first housing body 10 is not mounted on the adapter device 100 there is space to receive the second larger housing body 102. The assembly and disassembly of the larger housing body 102 in the adapter device 100 is carried out in a manner corresponding to that described for the first housing body 10, but instead of the first coupling structures 106 to 108 the second structures are employed coupling 110 to 112.

To further increase user comfort, the adapter device 100 has stop structures 114 that can be folded and deployed with respect to the support device 104 and which are designed so that after the first housing body 10 or the second housing body 102 has moved over the support device 104, the respective housing body 10, 102 collides in the abutment structures 114 in an interlocking position in which the respective housing body 10, 102 is interlocked or can be interlocked in the adapter device 100. Therefore, if the respective housing body 10, 102 collides with the abutment structures 114 on the front side, it is in the correct position, so that the retention feet 34 are located below of the respective interlocking bodies 108, 112 and the retention slides 40 of the respective housing body 10, 102 are in the position of the additional interlocking device 107, 111 respectively. In this way, intuitive and robust handling is possible against failures of the adapter device 100.

At the opposite edges of the front and rear side of the support device 104, adapter connection structures 118, 120 in the form of a mushroom are integrally provided. The adapter connection structures 118 are mushroom-shaped projections, while the adapter connection structures 120 are mushroom-shaped cutouts or recesses shaped and sized accordingly. Several adapter devices 100 of the type shown in Figure 5 and Figure 6 can be fixed to each other in series by introducing a respective mushroom-shaped shoulder with a positively shaped connection in a respective mushroom-shaped beading. In this coupled state the respective guide rails 106 or 110 of the attached adapter devices 100 are aligned with each other, so that in a corresponding state of displacement of the interlocking bodies 108 or 112 that the guide rails 106 and 110, a corresponding housing body 10, 102 can be moved through various adapter devices 100 to a desired target position.

The support device 104 has fixing structures 122 that pass through it vertically, which are made according to Figure 5 and Figure 6 in the form of through fixing holes to receive fixing screws and serve to fix the adapter device 100 in a body for fixing, as for example in a mounting kit 200 (see figure 9), an extension device 300 (see figure 11), a wall (not shown), etc.

By actuating drive elements 193 on a front side of the adapter device 100, not shown in Figure 5, a user can release a second housing body 102, which is mounted on the adapter device 100 in state 3, of the lock in front of displacement and, therefore, return it to state 2, since by this drive lever arms 195 (see Figure 6) can act on the retention slides 40 of the second housing body 102 inserted in the housing slots of the device of additional interlocking 111 of the suitcase.

A recess in the support device 104 forms a carrying handle 124 so that a user can transport the adapter device 100.

Referring now to Figure 6, the adapter device 100 further presents reinforcement structures 126 that are designed to make the support device 104 made of plastic more rigid. This increases the stability of the adapter device 100.

A non-slip protection device 116 on the side of the base to protect the adapter device 100 from a slip on an upholstered lower base (for example, in a trunk of a car covered with upholstery) is shown in Figure 6 in a separate state inactive in the support device 104 and shown in detail in Figure 8.

Figure 8 shows a non-slip protection strip of the non-slip protection device 116 with a barbed arrangement 118 of the adapter device 100 according to Figure 5 and Figure 6. According to Figure 6 the non-slip protection device 116 is in a fixed deactivated state on a base surface of the support device 104 and there away. The non-slip protection device 116 contains a two-dimensional arrangement of barbs 118 on the underside, which are designed to penetrate the lower carpet base when the adapter device 100 is placed thereon. The anti-skid protection device 116 can be selectively deactivated in the support device 104 (see Figure 6) or it can be moved to activate the anti-skid protection with respect to the support device 104. The anti-skid protection device 116 is formed by two sliding slats arranged in the support device 104 on the side of the base, which in the activated state can be arranged in a V-shape pointing towards each other on the lower side of the support device 104, protruding therefrom in the part lower. To move the anti-skid protection device 116 to an activated state, the sliding slats are removed from the inactive position shown in Figure 6 and locked in the support device 104 and temporarily removed from the support device 104 and inserted into slat receptacles 191 arranged angularly with each other on the lower side of the support device 104, so that the spikes 118 protrude on the lower side on the support device 104 and thereby be able to grip providing non-slip protection on a lower carpet base (not shown) . The non-slip slats are constructed in such a way that they can be housed positively with their narrow side in the slat housings 191 forming a plug connection and, on the other hand, they can be retracted vertically with their wide side in the sectional receptacles. of the support device 104.

Figure 9 shows a three-dimensional view of a mounting device 250 mounted on a car seat 202 formed by a mounting kit 200 which will be described in more detail below and an adapter device 100 mounted thereon in accordance with a type of exemplary embodiment of the invention. In addition, Figure 9 shows a detail 277 showing the assembly of connecting elements 206 of the mounting equipment 200 in fastening structures 208 of the car seat 202, which are attached to a body of a car containing the car seat 202. Some of the features of the mounting device 250 according to Figure 9 are also included in another mounting device 250 depicted in Figure 10 and Figures 12 to 15 and can be seen partially better there, so that in the following description for Figure 9, in part reference is also made to Figure 10 and Figures 12 to 15.

The mounting device 250 shown in Figure 9 is formed by the mounting equipment 200 as a mounting base and the adapter device 100 (in particular, the adapter device 100 shown in Figure 5 and Figure 6) for fixing of housing bodies 10, 102 in the car seat 202.

The adapter device 100 is mounted on a mounting structure 210 of the mounting equipment 200 using four threaded bolts in four corner regions of its support device 104. The threaded bolts are introduced through the fixing structures 122 of the adapter device 100, and inserted into the mounting structure 210 and the thread tightened. The mounting structure 210 therefore serves to mount the adapter device 100 such that its housing surface for fixing housing bodies 10, 102 at the top remains freely accessible for a user-defined assembly. The mounting structure 210 is formed by vertical and hollow metal tube parts, as can be better recognized in Figures 13 to 15, so that the threaded bolts are guided through the adapter device 100 and the metal tube parts , and there they are screwed. Each of the four threaded bolts has a corresponding drive (for example, an Allen drive) on an upper surface of the bolt head for applying a drive tool (for example, an Allen key).

The mounting equipment 200 comprises a base body 204 in the form of a metal rod construction similar to a carriage to be placed in the car seat 202 and to retain the adapter device 100 at a certain distance from the car seat 202.

The base body 204 is made as a construction of metal linkage formed by curved and partially welded hollow tubes. This linkage construction contains first rods 212 opposite each other, which run parallel to each other, and extend, for example substantially horizontally along a seating surface 214 of the car seat 202. The first rods 212 can be see only in part in Figure 9, since in the mounted state of the adapter device 100 they are below the adapter device 100. In this way a work surface of the upper side of the adapter device 110 is kept free and accessible to a user. for mounting or dismounting housing bodies 10, 102, even in a state of the mounting device 250 mounted on the car seat 202. In addition, the linkage construction has two second links 216 opposite each other and in a loop according to the figure 9 which extend, respectively, by sectors in the direction along or parallel to a backrest 218 of the car seat 20 2. As can be clearly seen in Figure 9, in the assembled state of the adapter device 100, one of the two second loop-shaped linkages 216 extends vertically over the adapter device 100 along a large part of the backrest 218 As a result, even if one or even relatively large housing bodies 10, 102 are mounted on the adapter device 200, the housing body (s) 10, 102 remains distanced (s) from the backrest 218, so that the second linkage 216 in contact with the backrest 218 acts as a spacer or impact protection for said housing bodies 10, 102. At the same time, the second linkage 216 in contact with the backrest 218 inhibits the inclination of the mounting device 250. The second linkage 216 adjacent to the backrest 218 extends, as shown in Figure 9, essentially more vertically upwards than the other second opposite linkage 216, which forms one end of the base body 204 further away from the backrest 218. In this way the entire housing surface of the adapter device 100 remains easily accessible to a user.

In addition, the mounting kit 200 contains two connecting elements 206 made in accordance with the Isofix standard (corresponding to ISO 13216, in particular in the 1999 or 2004 or 2006 version), which are arranged by means of a guide housing 224 (see Figure 10) respective screwed to the base body 204 and made here of plastic to receive a respective connecting element 206. If a respective one of the connecting elements 206 is inserted with positively connected in a respective one of the guide housings 224 (which can also be achieved by tensioning the flexible connecting elements 220 which will be described in more detail below), the elements connectors 206 are in a well defined position in which a non-tilting fixing of the mounting device 250 in the car seat 202 has been achieved. The connector elements 206 serve to anchor the mounting equipment 200 in the fixing structures 208 of the car seat 202, as shown in detail 277.

With reference now to detail 277, the connecting elements 206 of the mounting equipment 200 are made as Isofix connecting elements that are designed to be anchored in the Isofix fastening structures 208 of the car seat 202 rigidly attached to the car body. The connecting elements 206 can be inserted into the respective guide receptacles 224. Through the respective guide receptacles 224 flexible connector elements 220 are carried out as belts, at one end of which the connecting elements are placed. Through the respective guide receptacles 224 and a tensioning device 222, the connecting elements 206 mounted on the belts are fixed to the base body 204. A user to mount the mounting device 250 on the car seat 202 pulls out the connecting elements 206 outside the guide housings 224 and move them thanks to the flexibility of the connecting elements 220 to a desired position between the seating surface 214 and the backrest 218 of the car seat 202. The connecting elements 206 have retaining hooks that when they are introduced into the fixing structures 208 made as U-shaped hooks, they are hooked on them and thus form a secure click connection.

The mounting device 200 further presents the clearly recognizable tensioning device 222 in Figure 10 which is rigidly placed in the second linkage 216 of the base body 204 away from the backrest. One end of the flexible connection elements 220 furthest from the backrest 218 can be guided by the tensioning device 222. In this state, the flexible connection elements 220 can be tensioned by exerting a tensile force on the end of the flexible connection elements 220 and the tensioning device 222 can be operated by a user, after anchoring the connecting elements 206 in the fixing structures 208, fixing the flexible connecting elements 220 by tightening on the tensioning device 222 in the tensioned state. As can be recognized in Figure 1, the flexible connection elements 220 may be formed by a first belt, on which two connecting elements 206 are placed, and which is conducted through a loop at one end of a second belt. of the flexible connection elements 220, the second opposite end of the second belt being driven through the tensioning device 222. This belt construction achieves easy handling, reliable assembly, freedom of inclination and favorable force transmission .

Although not shown in the figure, the mounting device 200 may have an adjustment device that is configured to adjust a height and / or an inclination angle of the adapter device 100 mounted on the mounting equipment 200. In this way, without However, a horizontal work surface of the adapter device 100 can be provided on an inclined seat surface 214.

Likewise, wheels (not shown) on the lower side (screwable, for example) can be placed on the mounting equipment 200 so that in a separate state of the car seat 202, the mounting equipment 200 can be moved by rolling. Such placement of wheels in the mounting equipment 200 can be performed in a similar manner as shown in Figure 17 for wheels 312 of an extension device 300.

Figure 10 shows a view of the lower side of a mounting device 200, which is configured similarly to the mounting device 200 according to Figure 9, with the adapter device 100 mounted thereon. From figure 10 it can be deduced in particular that the flexible connection elements 220 have a first belt connecting the two connecting elements 206 to each other, and have a second belt with a tubular shaped end through which the first belt is introduced . An opposite end of the second belt is driven through the tensioning device 222.

Figure 11 shows an extension arrangement 380 according to an exemplary embodiment of the invention formed by an extension device 350 on the lower side, a storage box fixed thereto as a housing body 352 and an extension device 350 of the upper side mounted on the housing body 352. The lower side extension device 350 is comprised of a lower side extension device 300 and an adapter device 100 mounted thereon in accordance with Figure 5 and Figure 6. The upper side extension device 350 is composed of an upper side extension device 300 and another adapter device 100 according to Figures 5 and 6 and fixed to the upper side of the housing body 352, for example by screw connections. Although this is not shown in Figure 11, in the coupling structures 106 to 108, 110 to 112 on the upper side adapter device 100, at least one other housing body 10, 102 (not shown) can be mounted, for example a bag.

With reference numbers 304, 306, 312, 314 and 317 some components of the extension device 300 are represented or indicated. These components are explained in detail below with reference to Figures 16 to 20.

Figure 12 shows a housing arrangement 150 formed by a housing body 10 made as a suitcase (see Figures 1 to 4) for transporting transport goods and an adapter device 100 made for fixing 100 (see Figures 5 and 6) according to an exemplary embodiment of the invention, in which the adapter device 100 (and therefore the housing arrangement 150) in turn is mounted on the mounting equipment 200 according to figure 10. According to figure 12, the housing body 10 is not yet mounted on the adapter device 100. As an alternative to the housing body 10 a larger suitcase (see housing body 102 according to figure 18 or figure 19) can also be mounted on the adapter device 100. By means of closing devices 197, one of the respective housing bodies 10, 102 can be opened in a user-defined manner to gain access to a space inside or to be locked with interlocking.

The first housing body 10 has other first coupling structures 34, 36, 38, 40 (see the description for Figures 1 to 4), which are provided exclusively in the body 12 of the first housing body 10, and are positioned and sized to engage with the first coupling structures 106 to 108 of the adapter device 100. The second housing body 102, which can be mounted on the adapter device 100 as an alternative to the first housing body 10, has other second coupling structures 34, 36 , 38, 40 (see the description of Figures 1 to 4) exclusively in its body 12 (see Figure 18 or Figure 19) that are positioned and sized to engage with the second coupling structures 110 to 112 of the adapter device 100 .

The other first coupling structures 34, 36, 38, 40 and the other second coupling structures 34, 36, 38, 40 are made both for stacking secured against displacement, vertically detachable from the first housing body 10 or the second body of housing 102 in the adapter device 100 according to state 1, as well as to contribute to the coupling with each other in a non-removable manner vertically of the first housing body 10 or the second housing body 102 in the adapter device 100 according to the state 2 (without insurance against displacement) or state 3 (with insurance against displacement).

Figure 13 shows the housing arrangement 150 according to Figure 12 in state 1, in which the housing body 10 is disposed in the adapter device 100 vertically detachable and secured against displacement. Stacking one on top of another secured against vertically removable displacement is provided by housing grooves 36 on the lower side of retaining feet 34 in the outer edge regions of the lower side of the first housing body 10 (or the second housing body 102 ) and by corresponding projections of the interlocking structures 108 or 112 of the adapter device 100. It should be mentioned that the adapter device 100, the housing body 10 and the mounting device 200 together form a mounting arrangement 280 according to a type of exemplary embodiment of the invention.

Figure 14 shows the housing arrangement 150 according to Figure 12 in an operational state in which the housing body 10 is arranged according to the state 2 coupled to the adapter device 100 vertically not removable, but horizontally movable. The coupling on one another is not removable vertically is achieved by coupling heels 38 on the lower side of retaining feet 34 in the outer edge areas of the lower side of the first housing body 10 (or the second housing body 102) in cooperation with the interlocking structures 108 or 112 of the adapter device 100.

In addition, the other first coupling structures 34, 36, 38, 40 and the other second coupling structures 34, 36, 38, 40 are made such that, in cooperation with the first coupling structures 106 to 108 or the second coupling structures 110 to 112 of the adapter device 100, the first housing body 10 or the second housing body 102, on the one hand, and the adapter device 100, on the other hand, in the state coupled to each other in a manner they cannot be vertically removable, they can be selectively moved towards each other (see state 2 according to figure 14) or they can be secured against displacement by means of actuation especially of the coupling structures 40, 107, 111.

Figure 15 shows the housing arrangement 150 according to Figure 12 in state 3, in which the housing body 10 is arranged coupled with the adapter device 100 in a secured manner against horizontal displacement, not vertically removable. Securing against displacement in the state coupled to each other in a non-detachable manner vertically occurs by means of additional interlocking devices 107, 111 of the adapter device 100 made as housing slots in the support device 104 and corresponding retention slides 40 of the first housing body 10 or the second housing body 102 when the retention slides 40 are inserted into the housing slots 107, 111. According to Figure 14 the retention slides 40 are disengaged from the additional locking device 107 and, therefore, they allow a displacement between the adapter device 100 and the housing body 10 in the horizontal direction. According to FIG. 15, the retention slides 40 displaced downwards are now attached to the additional locking device 107 and, therefore, prevent a movement between the adapter device 100 and the housing body 10 in the horizontal direction.

The part of the coupling structures 40, 107, 111, which in the state 3 coupled to each other and not removable vertically contribute to the securing against displacement (see Figure 15), is made and can be operated independently of another part of the coupling structures 34, 36, 38, 106, 108, 110, 112 which contributes to the vertically secured detachable stack against displacement according to state 1 (see Figure 13), as well as to the coupling with each other in a way not removable vertically according to states 2 and 3 (see figure 14 and figure 15).

Figure 16 shows a three-dimensional view of an extension device 350 formed by an extension device 300 and an adapter plate 100 according to an exemplary embodiment of the invention. Figure 17 shows the extension device 350 according to Figure 16 in a view from the bottom side. Figure 18 shows an extension arrangement 380 formed by the extension device 350 according to Figure 16 and a housing body 102 mounted thereon (in the form of a suitcase larger than the suitcase forming the housing body 10 ), which is fixed to the adapter device 100 by means of the second coupling structures 110 to 112. Figure 19 shows the extension arrangement 380 according to Figure 18 with another housing body 10 of smaller size and with another adapter device 100 , so that the other adapter device 100 is fixed to the housing body 102 according to figure 18 and the other housing body 10 is fixed by the first coupling structures 106 to 108 to the other adapter device 100. Figure 20 finally shows a three-dimensional view of extension device 300 partially disassembled without adapter device 100.

The extension device 300 is used to spatially extend a housing surface of the adapter device 100, ie of the active surface of the adapter device 300 on which the coupling structures 106 to 108, 110 to 112 are arranged to couple the different bodies housing 10, 102, starting from the adapter device 100 open the possibility of discretionary fixing of an even larger housing body 352 (for example, a storage box, see Figure 11).

For this, the extension device 300 has a support structure 302 that is designed to support the adapter device 100 in four peripheral corner regions of its support device 104 and can be better recognized in Figure 17 and Figure 20. As It can be recognized in FIG. 20, four support blocks 331 are provided as part of the support structure 302, on which the adapter device 100 with physical contact rests. The support structure 302 is structurally configured to support the adapter device 100 exclusively in the region of two opposite side edges 188 of the adapter device 100, more precisely said in the four corner regions of the adapter device 100. Thus the other two lateral edges of the adapter device 100 remain largely freely accessible, which in particular favors a displacement of a respective housing body 10, 102 on the respective guide rails 106, 110 in the state of the adapter device 100 mounted on the device extension 300 (see for example figure 16). The support structure 302 is further configured to support the adapter device 100 exclusively by means of the support blocks 331 and, therefore, exclusively on a lower side of the adapter device 100 and in this way the housing surface of the side is completely released upper of the adapter device 100 for fixing housing bodies 10, 102. According to FIGS. 16 to 20, the support structure 302 is constituted by support elements 308 in the form of four support blocks 331 mounted in a slightly elastic manner and the struts connection 310 connecting the support elements 308. The support elements 308 are made of plastic, while the connection struts 310 are made of metal.

An extension structure 304 of the extension device 300, which is made of plastic, is configured to extend the housing surface of the adapter device 100 partially beyond its spatial limit in a state of the adapter device 100 supported by the support structure 302 Two U-shaped extension pieces of the extension device 300, at whose two ends, respectively, two support blocks 331 are in the assembled state, fit into one of the side edges 188 of the adapter device 100 and, therefore, they prolong this laterally. As can be seen in Figure 17, the lower side of the two U-shaped extension pieces of the extension device 300 is equipped with reinforcing struts 324 to increase the load capacity of the extension device 300. An upper surface ( also called the extension surface) of the two U-shaped extension pieces according to figures 16 and 8 to 20, serves to extend the housing surface of the adapter device 100. The extension structure 304 is therefore made to enlarge the device adapter 100 exclusively in the region of the two opposite side edges 188 and in adjacent corner regions 190 of the adapter device 100 (see Figure 16). Furthermore, the extension structure 304 is realized in such a way that in a state of the adapter device 100 supported by the support structure 302, the active housing surface of the adapter device 100 is substantially flush with the active extension surface of the structure extension 304 (see figure 16).

The extension structure 304 extends outward with a measure such that when the housing body 352 is exclusively fixed in the fixing structures 306 of the extension device 300, the extension structure 304 extends further outward than the housing body 352 hosted. Therefore, the U-shaped extension pieces also serve as impact protection for the housing body 352.

The fixing structures 306 which are made according to figures 16 to 20 in the form of four housing grooves on the extension surface of the U-shaped extension pieces, are formed on the extension surface of the extension structure 304 and They are specially designed for fixing feet or base areas of a housing body 352 made as a storage box (see Figure 11). It is advantageous for transport stability that the housing body 352 is supported exclusively by the extension device 300, not by the adapter device 100. Correspondingly when one of the housing bodies 10, 102 is fixed on the extension device 350, the transport load is received exclusively by the adapter device 100. It has been found that this charging logic is even more reliable than a support of a housing body 10, 102, 352 partly in the adapter device 100 and partly in the extension device 300.

Four wheels 312 are screwed on the lower side of the connection struts 310 which serve for the rolling movement of the extension device 300, including the adapter device 100. In order to avoid unwanted slipping of the extension device 300 if it is Whenever necessary, the wheels 312 are provided with locking structures 317. When a user operates the locking structures 317, the wheels 312 are prevented from moving.

In addition, an interlocking structure 314 is respectively placed on the lateral center of the two U-shaped extension pieces opposite each other in the extension structure 304 which serves to be interlocked with the housing body 352 when it is housed in the extension structure 304.

A connection structure 316 in the support blocks 331 and in the connection struts 310 is designed to connect the extension device 300 to the adapter device 100 by screwing a threaded mounting bolt.

In addition, it must be indicated to complete that “presenting” does not exclude other elements or stages and that “a” or “a” does not exclude a plurality. of the above embodiments can also be used in combination with other features or steps of other embodiments described above.The reference symbols in the claims should not be considered as limiting.
